The day is not far off when diabetics will be able to control blood glucose by applying a sticker-like patch inside the cheek like snuff and adding the right amount of insulin to the body.
Insulin is currently injected into the body through injections or pumps. But now Sabine Zionirites, a professor at the University of Leila in France, and colleagues from other countries have come up with an experimental patch. It contains insulin as a medicine and can stick to the inside of the cheeks and inject insulin into the blood.
This soft patch consists of three items. For one, it is made from a polymer nanofiber called polyacrylic acid. The beta-cyclo-dextran molecule is then added and finally some amount of graphene oxide is added.
In the next step, the small pieces were dipped in insulin solution for three hours. They were then applied to layers of skin inside the pigs' cheeks. They were heated by an infrared laser to 50 degrees Celsius for ten minutes.
Scientists found that insulin was released and began to be absorbed into the skin. Then three pigs with diabetes were taken. The patch was then heated externally for ten minutes and they began to release insulin. Each animal was grafted for ten minutes. Experts noted that their blood sugar levels immediately began to drop, so that in just 20 minutes, the entire dose of insulin reached the body.
The sticker on the inside of the cheek did not cause any scratches or adverse effects on the skin. Similar hypnotic grafts were applied to six humans for two hours without any adverse effects.
The next step is to further test the oral insulin graft system. The biggest advantage of this is that a sticker can be filled with insulin repeatedly.
